This one came to me in a dream last night, seriously. Interesting that the e-stock idea came up again today, it's kind of similar.

How about a "stock market" for memes? Basically, "buying and selling stock" in memes, "price" is whatever the market sets, drivers are perception of the trend direction and magnitude of the meme. Pretty sure there's no commercial app
here, though it'd be interesting to try and find correlates between meme prices and actual market behavior. More just a fun thing than anything else, but could be interesting. Certainly more evocative than, say, a game of Nomic. (Unless
you're a lawyer or a politician, I suppose.)
